Improved Shi-Tomasi sub-pixel corner detection based on super-wide field of view infrared images.

In this work, we propose a new, to the best of our knowledge, corner point detection method for a super-wide field of view infrared imaging system. First, the edge of the checkerboard calibration board is detected at the pixel level by morphological operation. Second, the interpolation technique is used to refine the edge so that the edge has sub-pixel accuracy.

A New Fault Feature Extraction Method for Rotating Machinery Based on Multiple Sensors.

During the operation of rotating machinery, the vibration signals measured by sensors are the aliasing signals of various vibration sources, and they contain strong noises. Conventional signal processing methods have difficulty separating the aliasing signals, which causes great difficulties in the condition monitoring and fault diagnosis of the equipment. The principle and method of blind source separation are introduced, and it is pointed out that the blind source separation algorithm is invalid in strong pulse noise environments.

Enhanced hydrophilic and antibacterial efficiencies by the synergetic effect TiO nanofiber and graphene oxide in cellulose acetate nanofibers.

In this study, a novel nanofiber with improved antibacterial efficiencies was created by introducing TiO nanofibers and graphene oxide (GO) sheets into cellulose acetate (CA) nanofibers using an efficient electrospinning process. The morphologies and chemical composition of above nanocomposite were fully measured by SEM, FTIR and XRD measurements. The results demonstrated that TiO nanofibers and GO sheets have a uniform distribution in the CA nanofibers and these two additives also could improve hydrophilicity.
